Write two properties of diamagnetic substance

Magnetism is an amazing force. You might sometimes wonder how such a phenomenon is possible. Every day, we come across objects such as water, wood, gold, etc., without even knowing that these materials show diamagnetism. These materials are diamagnetic materials that show the repelling property of the magnetic fields. A famous experiment was held in which a frog was levitated from a diamagnetic metal in the presence of other magnetic fields. Another experiment showed that water repels superconductors. It is terrific to see how these things can float and rise because of diamagnetism. Let’s look at what makes these materials diamagnetic and their applications. What are Diamagnetic Materials? Diamagnetic materials are materials and substances repelled by a magnetic field. That is because of the induced magnetic field created by the applied magnetic field in the opposite direction. An applied magnetic field induces a dipole in the material and the induced dipoles oppose the applied magnetic field. So, materials that have paired electrons are the property of diamagnetic materials. The material is known as diamagnetic, and this phenomenon is known as diamagnetism. Michael Faraday discovered diamagnetism in the 1840s, which Faraday’s Law can also prove. We can see diamagnetic materials in our day-to-day life such as water, some plastics, wood, etc. Discovery of Diamagnetism Brugmans first discovered diamagnetism in 1778. He first stated that magnetic fields repelled bismuth. It w...

The genesis of magnetism is due to the spin motion of electrons and their interactions with one another. Describing how materials respond to magnetism is the greatest approach to present different sorts of magnetic materials. You might be surprised to learn that all matter is magnetic. The main distinction is that certain materials have a higher magnetic permeability than others. What separates them is the degree of interaction between the magnetic moments. A few materials have no collective atomic magnetic moment interaction, whereas others have a high atomic magnetic moment interaction. Classification of Magnetic Materials The response of a material to an external magnetic force is defined by its magnetic characteristics. Solids may be divided into three categories based on their magnetic properties: • Ferromagnetic – materials that are attracted to magnetic materials strongly. Nickel, Cobalt and Iron are a few of its examples. • Paramagnetic – materials that are attracted to magnetic materials weakly. Molybdenum, Lithium and Magnesium are a few of its examples. • Diamagnetic – materials that aren’t attracted to magnetic fields. Gold, Water, Mercury, Bismuth and Copper are a few of its examples. What are Diamagnetic Materials? When put in a magnetic field, diamagnetic materials are those that are freely magnetised. The magnetization, on the other hand, is in the opposite direction of the magnetic field. Diamagnetism is the term for the magnetism displayed by certain mate...

• In a diamagnetic material, the magnetic lines of forces due to an applied field are repelled. • when suspended in a uniform magnetic field, diamagnetic materials set their longest axis at right angles to the direction of the field and the shortest axis is along the direction of the field. • when placed in a non-uniform magnetic field, the diamagnetic materials move from stronger parts of the field to the weaker parts. • relative magnetic permeability of diamagnetic materials is always less than unity that is μ r < 1 • Magnetic susceptibility if diamagnetic materials is always negative. • Magnetic susceptibility of diamagnetic materials does not change with temperature, that is they do not obey Curie law Reference: This article is referred from my book “electrical engineering materials” having ISBN 978-81-272-5069-0. In case of any doubt, you can put your question in the comment section.

This means that diamagnetic materials are repelled by magnetic fields. However, since diamagnetism is such a weak property, its effects are not observable in everyday life. For example, the magnetic susceptibility of diamagnets such a...

The term itself usually refers to the magnetic dipole moment. Anything that is magnetic, like a bar magnet or a loop of electric current, has a magnetic moment. A magnetic moment is a vector quantity, with a magnitude and a direction. An electron has an electron magnetic dipole moment, generated by the electron's intrinsic spin property, making it an electric charge in motion. There are many different magnetic behavior including paramagnetism, diamagnetism, and ferromagnetism. An interesting characteristic of transition metals is their ability to form magnets. Metal complexes that have unpaired electrons are magnetic. Since the last electrons reside in the d orbitals, this magnetism must be due to having unpaired d electrons. The spin of a single electron is denoted by the quantum number \(m_s\) as +(1/2) or –(1/2). This spin is negated when the electron is paired with another, b...

The magnetic forces of a material’s electrons will be changed when put in a magnetic field. Faraday’s law of magnetic induction describes this phenomenon. The magnetic properties determine how it responds to an external magnetic force. Materials are classified into three types by their response to externally applied magnetic fields: diamagnetic, paramagnetic, or ferromagnetic fields. Atoms of materials that show diamagnetic behaviour have no permanent magnetic dipole moment. When a diamagnetic material is introduced in an external magnetic field, a weak and slim magnetic dipole moment is induced in the direction of the applied field. Without applying a magnetic field, diamagnetic materials have no net magnetic moment (H). The spin motion of electrons and their interactions with one another are the origins of magnetism. When diamagnetic material is subjected to an external magnetic field, the spinning electrons undergo a motion that produces an electrical current, resulting in magnetisation in the opposite direction of the magnetic field. When an electron in an atomic orbit moves through a magnetic field, the force applied on the electron causes a slight shift in orbital motion; the electron orbit processes around the magnetic field’s direction. The properties of diamagnetic materials vary in nature. What are the different types of magnetic properties? The magnetic properties possessed by the atoms and ions of a material are responsible for the magnetic properties shown by ...
